Question

In which part of the chloroplast does each stage occur?

Answer 1

Answer:

The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).

Answer 2

In the thylakoid membrane of the chloroplast, each stage of light reaction occurs. While in the stroma of chloroplast, the dark reaction occurs.

• Grana and stroma are parts of the chloroplast.
• The stacks of thylakoid are referred to as grana. Thylakoid is the internal membrane forming the site for light reactions.
• All the photochemical, as well as the reactions of electron transfer, take place in this thylakoid membrane.
• Stroma is the site for dark reactions. Stroma is a matrix containing dense fluid.
